On Monday, President Obama will join Chinese President Xi Jinping, German Chancellor Angela Merkel, and 40 other heads of state in the Netherlands for the 2014 Nuclear Security Summit. It will be the third in a series of summits initiated by Obama to address what he has called “the most immediate and extreme threat to global security”: nuclear terrorism. These gatherings have become a powerful means of motivating leaders to eliminate or secure the fissile material that terrorists could use to carry out a nuclear 9/11.

In a Feb. 25 West Point speech, Secretary of Defese Robert Gates proposed a radical prescription for defense policy. If his view were adopted, the “Gates Doctrine’’ would be his most important legacy. In his words: “Any future defense secretary who advises the president to again send a big American land army into Asia or into the Middle East or Africa should have his head examined.’’

"President Obama should announce immediately full U.S. support for a British-French led No Fly Zone over Libya," writes Graham Allison. "He should express confidence in the British and French to organize and conduct this military operation with the backing of their colleagues in the 27-nation European Union and NATO. The US should stand ready to respond to requests for help if we have unique capabilities, including intelligence assets, essential for this mission." The U.S. should not take the lead, Allison argues.

Is it possible for the U.S. to promote democracy and pluralism?? The democratic revolutions of 1989, coupled with the retreat of authoritarian regimes in Latin America and part of Asia and Africa, have prompted a resurgence of interest throughout the U.S. government and society at large in promoting democracy.

As the policy community prepares to assess an agreement between the U.S. and its P5+1 partners and Iran, Senate Foreign Relations Committee Chairman Bob Corker asked me to review the history of analogous agreements for lessons that illuminate the current challenge. In response to his assignment, I reviewed the seven decades of the nuclear era, during which the U.S. negotiated arms-control treaties, including the Non-Proliferation Treaty of 1968; strategic arms limitation talks and agreements from SALT to New Start; the North Korean accord of 1994; the agreements that helped eliminate nuclear weapons in Ukraine, Kazakhstan, and Belarus in the early 1990s; and the pact that eliminated the Libyan nuclear weapons program in 2003.

Among many lessons and clues from this instructive history, five stand out

Belfer Center Director Graham Allison testified before the U.S. Senate Committee on Foreign Relations on "Lessons Learned from Past WMD Negotiations" to inform assessment of a comprehensive nuclear deal that will prevent Iran from acquiring nuclear weapons.

"This week, with little fanfare, one of the world’s key restraints on the spread of nuclear weapons came under scrutiny, as a month-long review of the Non-Proliferation Treaty (NPT) concluded at the United Nations," writes Graham Allison. "Negotiated over the 1960s, the NPT was signed in 1968 and became international law in 1970. As specified by the treaty, members hold a conference every five years to assess the agreement. The exercise offers insight into our nuclear age, and perspective ahead of the coming debate over a treaty to constrain Iran’s nuclear ambitions."

Nuclear Terrorism: The Ultimate Preventable Catastrophe

Graham Allison, founding dean of Harvard’s Kennedy School of Government, a former top official at the Pentagon, and one of America’s leading scholars of nuclear strategy and national security, presents the evidence and argument that led him to two provocative conclusions: a nuclear terrorist attack on an American city is inevitable on our current course and speed, but preventable if we act now.
